We have an opportunity to visit Glasgow for the day tomorrow. DH is umming and ahhing about whether it's worth it. We love Edinburgh, the quirkiness and the history of it. However, will Glasgow be a let down in comparison? I can't think of any sights in Glasgow and DH says there is nothing of historical interest there....but I really wanted to see it just the once anyway. Please tell me is it worth a visit? What is a must-see if we go?
